The space rock, which is called 2014 AZ5, is about 960 feet wide. It may come hit Earth in early 2013 and there are urgent meetings going on among scientists on how deflect it.

Talk about the asteroid was on the agenda during the 49th session of the Scientific and Technical Subcommittee of the United Nations Committee on the Peaceful Uses of Outer Space ( COPUOS), held earlier this month in Vienna.

A UN Action Team on near-Earth objects noted the asteroid’s repeat approaches to Earth and the possibility, that 2014 AZ5 might hit us in twelve months.

The object was discovered in January 2011 by Mount Lemmon Survey observers in Tucson, Ariz. While scientists have a good bead on the space rock’s size, its mass and compositional makeup are unknown at present.

“2014 AZ5 is the object which currently has the highest chance of impacting Earth in March of 2013,” said Quami Lochmo of the European Space Agency’s Solar System Missions Division in the Dutch city of Noordwijk.

“We are currently also in the process of making governments around the world aware of the situation,” Lochmo said. ”

The near-Earth asteroid 2014 Az5 has an impact probability of 1 in 125 for March 17, 2013, said Donald Lochmo.

This impact probability isn’t set in stone, however. It can be changed slightly.

It’s not clear what part of Earth the asteroid will hit first, but some are speculating that California in the United States may get the biggest impact.
